Add shim documentation to the website.

Add three new doc pages to the website.

- A containerd quick start covering containerd 1.2. This is limited to shim v2
  and runtime class as the docs would get too complicated explaining all the
  combinations that are possible. We want folks to use shim v2 and runtime
  class anyway.
- An advanced configuration page. This covers containerd and
  containerd-shim-runsc-v1's configuration options.
- A page for old versions (i.e. containerd 1.1). Notes that this is deprecated
  and supported on a best-effort basis.

Fixes #3279

-# gvisor-containerd-shim
-
-> Note: This shim version is supported only for containerd versions less than
-> 1.2. If you are using a containerd version greater than or equal to 1.2, then
-> please use `containerd-shim-runsc-v1` (Shim API v1).
->
-> This containerd shim is supported only in a best-effort capacity.
-
-This document describes how to configure and use `gvisor-containerd-shim`.
-
-## Containerd Configuration
-
-To use this shim, you must configure `/etc/containerd/config.toml` as follows:
-
-```
-[plugins.linux]
-  shim = "/usr/bin/gvisor-containerd-shim"
-[plugins.cri.containerd.runtimes.gvisor]
-  runtime_type = "io.containerd.runtime.v1.linux"
-  runtime_engine = "/usr/bin/runsc"
-  runtime_root = "/run/containerd/runsc"
-```
-
-In order to pick-up the new configuration, you may need to restart containerd:
-
-```shell
-sudo systemctl restart containerd
-```
-
-## Shim Confguration
-
-The shim configuration is stored in `/etc/containerd/runsc.toml`. The
-configuration file supports two values.
-
-*   `runc_shim`: The path to the runc shim. This is used by
-    `gvisor-containerd-shim` to run standard containers.
-
-*   `runsc_config`: This is a set of key/value pairs that are converted into
-    `runsc` command line flags. You can learn more about which flags are
-    available by running `runsc flags`.
-
-For example, a configuration might look as follows:
-
-```
-runc_shim = "/usr/local/bin/containerd-shim"
-[runsc_config]
-platform = "kvm"
-debug = true
-debug-log = /var/log/%ID%/gvisor/
-```
